Notes. For each parameter, Nsample values are simulated in the values range. As the best fits were obtained with a double exponential SFH (sfh2exp), we report only the parameter space for this SFH, while the other investigated SFHs are indicated in SFH: the delayed SFH (sfhdelayed), the delayed SFH with a burst (sfhdelayedbq), and the periodic SFH (sfhperiodic).
